We spent 17 days with Ciro in November-December 2009, and visited almost all the good sites in NE Brazil. Ciro is a hard worker when it comes to getting the birds for his clients. He also has the best ears that I have ever encountered – he not only hears little squeaks in the forest identifies them and then has an ability to get the birds to respond and provide great views!
Thanks to his abilities, we saw 99% on the birds we were looking for – including some mega-rarities.
I highly recommend Ciro to any birder interested in that part of Brazil
